  1. Tactical problems are not only evaluated on material; a full assessment of the position is made also. It's my opinion that this makes the training more complete since you have to consider not only the tactical motif but the entire game.
  2. In every tactics problem you need to gain a least 2 pawns equivalent score. Considering point 1 above; it is possible that the correct solution implies a material gain of only one pawn and the other one is achieved by positional elements.
  3. If you make a move that is weaker than the best one, but its score is greater than the equivalent of 2 pawns value, the system tells you that is a good move but that there is a better one and lets you retry. If the move score is under 2 pawns your solution is considered wrong.
  4. For the last required move; if its score is over 5 pawns the problem is considered correctly solved even if there is a better solution from the computers point of view.
  5. The solution always shows the complete computer best line but only the moves in bold typeface are required to successfully resolve the problem.

Ultimately; I can now say that within ideachess; beside the tactics training, there is also a strategic component to the training.

Italian version:

  1. A differenza di prima, ora nei problemi di tattica non viene valutato solo il materiale, ma viene fatta una valutazione complessiva della posizione. Ritengo che in questo modo l'allenamento sia più completo in quanto non va considerato solo il motivo tattico ma la partita nella sua interezza.
  2. In ogni problema di tattica si deve migliorare la posizione di un punteggio equivalente ad almeno 2 pedoni. Considerando il punto 1. è possibile che la soluzione corretta implichi il guadagno di un pedone come materiale e che il restante pedone sia ottenuto da elementi posizionali.
  3. Se viene eseguita una mossa più debole della migliore ma il cui punteggio è superiore all'equivalente di 2 pedoni il sistema comunica che si tratta di una buona mossa ma ce n'è una migliore e chiede di riprovare. Se il punteggio del tentativo è inferiore ai 2 pedoni l'esercizio è considerato sbagiato.
  4. Solo per l'ultima mossa della soluzione richiesta se questa, pur non essendo la migliore, è valutata con punteggio uguale o superiore ai 5 pedoni il problema viene comunque considerato risolto correttamente.
  5. Nella soluzione viene sempre mostrata per intero la migliore linea identificata dal computer tuttavia solo le mosse in grassetto sono richieste al giocatore affinchè il problema sia considerato risolto.

In definitiva posso dire che ora per la risoluzione degli esercizi di Ideachess è necessaria oltre ad una analisi tattica anche un analisi strategica della posizione.

queste variazioni, che sono fondamentali, non si potrebbero avere anche in italiano, vista la maggioranza di utenti di lingua italica? lo so, l'inglese è lingua internazionale, ed è giusto che ci sia, ma essendo il sito italiano forse lasciare l'opportunità della lingua madre per i più ignoranti come me non sarebbe sgradito...grazie improbable

The change may be for the better - but you used to have a feature that you no longer have, but which was very useful.

Now, if I make a move which the program doesn't evaluate highly, I get immediately the 'wrong' notice.

Before, the computer would play 4 or 5 moves with me before telling me that I'm wrong. The benefit was that I got to play my idea out and see why it doesn't bring the expected result. It also happens that computer doesn't immediately see why an idea is good, but after several moves the evaluation goes up,

Conclusion: even for evaluations under 2, please let us play for several moves before dropping the 'wrong' thing over our heads...

thanks!!

I don't mind the immediate 'wrong' notice, but I think the user should be able to continue nevertheless, particularly if the evaluation of the 'internal chess engine that evaluates alternative solutions' indicates a clear refutation of the solution attempt.

Hi,
this really is a very good site.

Is it possible to have an option to exclude the "mate in X" problems so that a player can just focus on the tactics? This would improve the site greatly for training purposes.

Although many of the mate in 2/3 moves are useful many of the mate in 4-5-6 are really for problem solving and of little value to a tournament player looking for tactical practice.

If a solution is only correct because it avoids suicide Q sacs etc its really not relevant to the thought process in a game....actually is quite harmful as we should be learning to quickly dismiss moves that just leave position totally lost.Also some of the mate in 5 or 6 are seriously difficult and again of little relecance even for master level tournament play.

If people want them then they can choose to solve them if the option is there.

I do miss seeing the computer's line against alternative moves. I think that this was a neat feature to have and (except on the few occasions when I and Fritz (very few occasions! :oops: ) thought the computer line was not the best one) represented a learning experience. On some of the more complex problems it's not always obvious what the refutation is. The long "main line" is often interesting, but I do not think it's as educational as exploring other mistaken possibilities.
